高中英语 语法陷阱题800例-名词性从句
高中英语语法名词性从句(附练习题)
名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。
而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。
被强调部分指人时也可用who/whom。
例如：a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
b) It doesn’t interest me whether you succeed or not. 我对你成功与否不感兴趣。
c) It is in the morning that the murder took place. 谋杀案是在早上发生的。
（强调句型）d) It is John that broke the window. 是John打碎的窗户。
（强调句型）2. 用it 作形式主语的结构(1) It is ＋名词＋从句It is a fact that … 事实是…It is an honor that …非常荣幸It is common knowledge that …是常识(2) It is ＋形容词＋从句It is natural that… 很自然…It is strange that… 奇怪的是…(3) It is ＋不及物动词＋从句It seems that… 似乎…It happened that… 碰巧…It appears that… 似乎…(4) It ＋过去分词＋从句It is reported that… 据报道…It has been proved that… 已证实…It is said that… 据说…3. 主语从句不可位于句首的五种情况：（1）if 引导的主语从句不可居于复合句句首。

高考英语语法名词性从句专题讲解练习含答案
名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句是一种具有名词功能的非独立分句。
具体用法见下表：主语从句大多数主语从句都可以用it作形式主语而把主语从句置于句尾。
(what引导的主语从句表示“……的东西”时，一般不用it作形式主语；whatever, whoever, whichever一般也不用it作形式主语。
)►It makes no difference where we shall have the meeting.我们在哪开会无所谓。
【注意】(1)常见的it替代that引导的主语从句的句式主要有以下几种：①It＋系动词＋形容词(necessary/right/likely/important/certain...)＋that从句②It＋be＋名词(短语)(a pity/a shame/good news/a fact/an honour...)＋that从句③It＋be＋过去分词(said/told/heard/reported/decided/suggested...)＋that从句④It＋特殊动词(seem/appear/happen/matter)＋that从句(2)在“It is necessary/important/natural...＋that从句”的结构中，从句谓语常用“(should ＋)动词原形”。
宾语从句1．动词find, feel, think, consider, make, believe等后有that引导的宾语从句作宾语补足语时，则常用it作形式宾语而将that宾语从句后置。
►I think it necessary that we take plenty of boiled water every day.我认为每天摄入足量的白开水很有必要。
2．有些动词(短语)不能直接跟宾语从句，需要借助形式宾语it。
常见的有hate, enjoy, like, dislike, love, appreciate, see to等。

高中英语 语法陷阱题800例
高中英语语法陷阱题800例-名词性从句◆典型陷阱题分析◆1. She was so angry and spoke so fast that none of us understood _______ he said meant.A. thatB. whatC. that thatD. what what【陷阱】可能误选B。
许多同学一看选项首先就排除了C和D，认为这样两个“引导词”叠用的情况不太可能。
在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择了B。
【分析】正确答案选D。
第一个what 用作动词meant 的宾语，第二个what 用作动词said 的宾语，即在none of us understood what what he said meant 中，none of us understood 为主句，what whathe said meant 为宾语从句，而在此宾语从句中又包括有what he said 这样一个主语从句。
2. After _______ had happened he could not continue to work there.A. whichB. howC. whatD. having【陷阱】可能误选A。
【分析】最佳答案选C。
有的同学误选A，是因为认为介词后应接关系代词which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。
另外，由于had happened 缺主语，所以B和D也不能选。
请再做下面一题(答案选B)：He pointed to ______ looked like a tomb and said, “Ghost.”A. thatB. whatC. whichD. as3．“Is ______ you want to say?”asked the teacher.A. thisB. thatC. all thatD. that all【陷阱】根据中文字面意思误选A或B。

高中英语 高考语法易错知识点15.名词性从句(考点梳理+易错点)
名词性从句知识梳理1. 名词性从句的概念名词性从句是在句子中起名词作用的句子。
名词性从句的功能相当于名词词组，它在复合句中能充当主语、宾语、表语和同位语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句，表语从句，宾语从句和同位语从句。
2. 名词性从句的连接词★连接词：that，whether，if，as if。
that 无词义，在从句中不担任成分，有时可省略；if/whether（是否），as if（似乎）虽有词义，但在从句中不担任成分。
★连接代词：who，whose，whom，what，which。
有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
★连接副词：when，where，why，how。
有词义，在从句中担任成分，作状语。
易错知识点1. 误用名词性从句的连接词名词性从句的连接代词与连接副词在从句充当句子成分，连接词whether和if（是否），as if（好像）在从句中不充当句子成分，只起连接作用。
根据句义，如果连接代词与连接副词，whether、if 和as if 都用不上时，才用that作连接词（that本身无任何含义）。
1.1 易错例题 1At first he hated the new job but decided to give himself a few months to see ____ it got any better.A. whenB. howC. whyD. if【陷阱】考生容易误选A，混淆名词性从句中的连接词和连接副词的使用，认为是看什么时候情况会变得好一点。
【分析】最佳答案D，句子的意思是：最初他不喜欢这份新工作，但是他决定给自己几个月的时间来看一下这件工作是否会变得更好。
see后面是名词性从句中的宾语从句，且宾语从句中成分完整，故用if引导宾语从句。
【考题再现】What the doctors really doubt is _____ my mother will recover from the serous disease soon.A. whenB. howC. whetherD. Why【陷阱】考生容易误选B，注意文中表达的是“是否”之意，而非“怎样”。
高考名词性从句详细讲解及易错题汇总解析
高考英语名词性从句详细讲解及易错题汇总解析一、名词性从句定义：在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、宾语从句、表语从句和同位语从句。
主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。
引导名词性从句的连接词可分为三类：连接词：that, whether, if （不充当从句的任何成分）连接代词：what, whatever, who, whoever, whom, whose, which.连接副词：when, where, how, why1. 主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词that，whether，if 和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。
that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
What he wants to tell us is not clear.It is known to us how he became a writer.Where the English evening will be held has not yet been announced.有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句（3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句注意：在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…2. 宾语从句名词句用作宾语的从句叫宾语从句。

专题08 名词性从句陷阱题高中英语语法易错题通关秘籍 Word版含解析
第一部分：理论知识由一个主句和一个或一个以上的从句构成的句子叫复合句。
名词性从句在复合句中起名词的作用，它包括主语从句、宾语从句、表语从句、同位语从句四大类，在句中分别用作主语、宾语、表语和同位语。
一、引导名词性从句的关联词A．that连词that本身没有意义，在从句中不担任任何句子成分，在宾语从句中有时可省略。
I hear (that) he has joined the football club. 我听说他已经加入了足球俱乐部。
That light travels in straight line is known to all. 众所周知，光是以直线传播的。
It so happens that I know the man. 碰巧我认识那个。
Is it certain that they will win 他们一定会赢吗B．whether和if连词whether和if本身有意义（解释是否），在从句中不可省略。
1．whether可以连接所有的名词性从句，而if只能引导宾语从句。
I didn't know whether he would attend the concert. 我并不知道他是否参加音乐会。
（宾语从句，可用if代替whether）The question is whether it s worth trying. 问题是值不值得试一试。
（表语从句，不可用if代替whether）Whether she comes or not makes no difference. 她来不来都没有关系。
（主语从句，不可用if代替whether）He must answer the question whether he agrees to it or not. 他必须回答他是否同意此事这样一个问题。
（同位语从句，不可用if代替whether）2．whether引导的宾语从句可作介的宾语，而if则不能。

; 苹果售后维修点 / 苹果售后维修点 ；
顿写一封内容尖刻的信回敬那家伙。 “可以狠狠地骂他一顿。”林肯说。 斯坦顿立刻写了一封措辞强烈的信，然后拿给总统看。 “对了，对了。”林肯高声叫好，“要的就是这个！好好训他一顿，真写绝了，斯坦顿。” 但是当斯坦顿把信叠好装进信封里时，林肯却 叫住他，问道：“你要干什么？” “寄出去呀。”斯坦顿有些摸不着头脑了。 “不要胡闹。”林肯大声说，“这封信不能发，快把它扔到炉子里去。凡是生气时写的信，我都是这么处理的。这封信写得好，写的时候你己经解了气，现在感觉好多了吧，那么就请你把它烧掉，再 写第二封信吧。” 6、果断 有一个6岁的小男孩，一天在外面玩耍时，发现了一个鸟巢被风从树上吹掉在地，从里面滚出了一个嗷嗷待哺的小麻雀。小男孩决定把它带回家喂养。 当他托着鸟巢走到家门口的时候，他突然想起妈妈不允许他在家里养小动物。于是，他轻轻地把小 麻雀放在门口，急忙走进屋去请求妈妈。在他的哀求下妈妈终于破例答应了。 小男孩兴奋地跑到门口，不料小麻雀已经不见了，他看见一只黑猫正在意犹未尽舔着嘴巴。小男孩为此伤心了很久。但从此他也记住了一个教训：只要是自己认定的事情，决不可优柔寡断。这个小男孩长 大后成就了一番事业，他就是华裔电脑名人—王安博士。 7、将军和驴子 古罗马皇帝哈德良曾经碰到过这样一个问题。 皇帝手下的一位将军，觉得他应该得到提升，便在皇帝面前提到这件事，以他的长久服役为理由。“我应该升更重要的领导岗位”，他报告，“因为，我的经 验丰富，参加过10次重要战役。” 哈德良皇帝是一个对人及才华有着高明判断力的人，他不认为这位将军有能力担任更高的职务，于是他随意指着绑在周围的战驴说： “亲爱的将军，好好看这些驴子，它们至少参加过20次战役，可他们仍然是驴子。” 8、马蝇效应 1860 年美国总统大选结束后，林肯当选为总统。他任命参议员萨蒙?蔡斯为财政部长。 有许多人反对这一任命。因为蔡斯虽然能干，但十分狂妄自大，他本想入主白宫，却输给了林肯，他认为自己比林肯要强得多，对林肯也非常不满，并且一如既往地追求总统职位。 林肯对关心他 的朋友讲了这样一个故事： “在农村长大的朋友们一定知道什么是马蝇了。有一次，我和我的兄弟在肯塔基老家的一个农场犁玉米地，我吆马，他扶犁。这匹马很懒，但有一段时间它却在地里跑得飞快，连我这双长腿都差点跟不上。到了地头，我发现有一只很大的马蝇叮在它身上 ，我随手就把马蝇打落了。我兄弟问我为什么要打落它，我说我不忍心看着这匹马那样被咬。我兄弟说：“唉呀，正是这家伙才使马跑得快嘛。” 然后，林肯说：“如果现在有一只叫‘总统欲’的马蝇正叮着蔡斯先生，那么只要它能使蔡斯和他的那个部不停地跑，我就不想去打落 它。” 9、潜水艇中的15个小时 二战快结束时，有个叫罗勃?摩尔的小伙子正在海军服役。他讲述了亲身经历的一件事。 "1945年3月，我在中南半岛附近276英尺的海下，学习到了人生最重要的一课。当时我正在一艘潜水艇上，我们从雷达上发现了一支日本舰队—— 一艘驱逐 护航舰、 一艘油轮和一艘布雷舰朝我们这边开过来。我们发射了五枚鱼雷，都没有击中。突然那艘布雷舰直朝我们开来 (一架日本飞机把我们的位置用无线电通知了它)。我们潜到150英尺深的地方，以免被它侦察到，同时做好应付深水炸弹的准备，还关闭了冷却系统和所有的发电机。 "3分钟后，天崩地裂。6枚深水炸弹在四周炸开，把我们直压海底 276英尺的地方。深水炸弹不停地投下，整整15个小时，有十几个二十个就在离我们50英尺左右的地方爆炸 要是深水炸弹距离潜水艇不到17英尺的话，潜艇就会炸出洞来。 "当时，我们奉命静静地躺在自己的床上，保 持镇定。 我吓得几乎无法呼吸，不停地对自己说: 。这下可死定了。潜水艇的温度几乎有摄氏40度，可我却怕得全身发冷，一阵阵冒冷汗。15个小时后，攻击停止了，显然那艘布雷舰用光了所有的炸弹而离开了。 "这15个小时，在我感觉好像有1500万年，我过去的生活一一在眼前 出现，我记起了做过的所有坏事和曾经担心过的一些很无聊的小事。我曾经担心过:没有钱买自己的房子，没有钱买车，没有钱给妻子买衣服。下班回家，常常和妻子为一点芝麻小事而争吵。我还为我额头上的一个小疤——一次车祸留下的伤痕——发过愁。 "所有这些年来的愁苦烦 恼，在此时此刻都显得那么荒谬、渺小，而我过去居然对他们很在意。" 10、参照标准 一个人去买碗，他懂得一些识别瓷器质量的方法，即用一只碗轻撞其它碗，发出清脆声音的碗肯定是质地好的。但来到店里，他却发现每一只碗发出的声音都不够清脆。最后店员拿出价格高昂的 工艺碗，结果还是让他不甚满意。店员最后不解地问：“你为什么拿着碗轻撞它呢？”那人说这是一种辨别瓷器质量的方法。 店员一听，立即取过一只质量上好的碗交给他：“你用这只碗去试试。”他换了碗，再去轻撞其它的碗，声音变得铿锵起来。 原来他手中拿着的是一只 质地很差的碗，它去轻碰每一只碗，都会发出混浊之音。合作者变了，参照标准变了，一切也就变了。 生活也是如此，你的参照标准如果错了，那么你眼中的整个世界也就错了。 11、最深刻的记忆 美国普林斯顿大学教授丹尼尔?卡尼曼将心理学的知识引入经济学，并因此获得2002 年诺贝尔经济学奖。 卡尼曼得出的结论看上去颇为荒谬，甚至违反直觉。1996 年，卡尼曼做了一个最为有名的实验，他研究了682 名做结肠镜检查的患者。他将病人随机分为两组，其中一组病人的结肠镜检查稍做延长，即检查结束后，先不抽出管子，而是静静地放一会儿，这时候 病人会感到不舒服，但已没什么大痛。做延长检查的病人（不管开始阶段有多么痛苦）事后都反应不错，觉得下次选择还是要选结肠镜而不是钡餐和X光。而那些没有延长检查时间的病人下来后则大叫：“真像下地狱啊。” 卡尼曼由此得出结论：“我们在评价某种经验时，有一个时 间长短的因素。也就是说，最后阶段的痛苦（或欣悦）程度决定了我们对整个事件的记忆与评价。这对我们预期某种决策以及每天利用这一“捷径”做出上百个决定极为有用。 12、热爱的奇迹 美国西部电器公司委托著名的梅奥教授，希望他能使下属的一家工厂里的女工提高生产效 率。 根据这些工人从事的非常单调的电磁铁绕线圈的工作，梅奥提出下午让工人们有10分钟的喝咖啡的休息时间，结果产量立刻增长。这时，梅奥进一步在上午也给工人10分钟喝咖啡的休息时间，生产再次增长。 但是，梅奥没有就此罢手，他开始宣布取消了下午的休息时间， 产量仍在增长；接着他又取消了上午的喝咖啡时间，但是产量继续增长着，工人们没有抱怨和怠工现象。这是为什么呢？ 这项工作的确是单调枯燥的。当有了休息后，工人们都喜欢这一段轻松愉快的时间，他们互相说笑着，谈论着感兴趣的话题。当听到梅奥向她们解释了她们在参 与一个实验。她们就感到自己正在一个有意义的程序中工作，有光荣的参与感。不知不觉中她们热爱上了这项工作，热爱上了这个集体。 于是这推动了工业心理学一个新的探索：热爱或兴趣似乎比休息、增加报酬等更能提高人们的生产力。热爱让我们无论身处什么样的环境，而精 神都住在一个自由、美丽的天堂里。热爱应该成为我们的生存内容之一。 13、看着我的眼睛 2002年，德国发生了一桩血案。一个19岁的小伙子，2001年留级，2002年又因伪造假条，被校方开除。他决心报复学校。4月26日上午，他戴着恐怖的面具，一手握一支手枪，一手拎着连发 猎枪，闯进学校，见人就打，主要是瞄准老师，他觉得是他们让他蒙受了羞辱。在20分钟的疯狂射击中，他的手枪共打出了40发子弹，将17人打死，其中有13名老师。他还有大量的子弹，足够把数百人送进坟墓。这时候，他的历史老师海泽先生走过来，抓住他的衬衣，试图同他说话。这 个血洗了母校的学生认出了他的老师，他摘掉了自己的面具。海泽先生叫着他的名字说，罗伯特，扣动你的扳机吧。如果你现在向我射击，那就看着我的眼睛!那个杀人杀红了眼的学生，盯着海泽先生看了一会儿，缓缓地放下了手枪，说，先生，我今天已经足够了。后来海泽先生把凶手 推进了一间教室，猛地关门，上了锁。此后不久，凶手在教室里饮弹自杀。 我惊讶海泽先生的勇敢，更惊讶他在这种千钧一发之时说出的这句话。 正是这句话，唤起了凶手残存的最后一丝良知，停止了暴行。 海泽先生是非常自信的。这不是一种技巧，而是一种坚定的修 养。是一种长期潜移默化修炼提升的结果。一位老师所有的岁月和经验，就化成了超人的勇气和智慧。 14、命令是这样传递的 据说，美军1910 年的一次部队的命令传递是这样的： 营长对值班军官：明晚大约8点钟左右，哈雷彗星将可能在这个地区被看到，这种彗星每隔76年 才能看见一次。命令所有士兵着野战服在操场上集合，我将向他们解释这一罕见的现象。如果下雨，就在礼堂集合，我为他们放一部有关彗星的影片。 值班军官对连长：根据营长的命令，明晚8点哈雷彗星将在操场上空出现。如下雨，就让士兵穿着野战服列队前往礼堂，这一罕见 的现象将在那里出现。 连长对排长：根据营长的命令，明晚8点，非凡的哈雷彗星将身穿野战服在礼堂中出现。如果操场上下雨，营长将下达另一个命令，这种命令每隔76年才会出现一次。 排长对班长：明晚8点，营长将带着哈雷彗星在礼堂中出现，这是每隔76年才有的事。如 果下雨，营长将命令彗星穿上野战服到操场上去。 班长对士兵：在明晚8点下雨的时候，著名的76岁哈雷将军将身着野战服，开着他那“彗星”牌汽车，经过操场前往礼堂。 15、死亡暗示 非洲刚果有个黑人青年在朋友家作客，朋友准备了一只野鸡作为早餐。黑人青年的部落严 禁吃野鸡，他就问朋友，早点是不是野鸡。朋友答，不是野鸡。黑人青年便享受了一顿美味的早餐。数年后，他们二人再次见面。那位朋友问他想不想吃野鸡，青年回答说那是不可能的，因为巫师郑重警告过他绝不可以吃野鸡。

高中英语语法陷阱题800例-名词性从句
◆典型陷阱题分析◆
1. She was so angry and spoke so fast that none of us understood _______ he said meant.
A. that
B. what
C. that that
D. what what
【陷阱】可能误选B。
许多同学一看选项首先就排除了C和D，认为这样两个“引导词”叠用的情况不太可能。
在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择了B。
【分析】正确答案选D。
第一个what 用作动词meant 的宾语，第二个what 用作动词said 的宾语，即在none of us understood what what he said meant 中，none of us understood 为主句，what whathe said meant 为宾语从句，而在此宾语从句中又包括有what he said 这样一个主语从句。
2. After _______ had happened he could not continue to work there.
A. which
B. how
C. what
D. having
【陷阱】可能误选A。
【分析】最佳答案选C。
有的同学误选A，是因为认为介词后应接关系代词which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。
另外，由于had happened 缺主语，所以B和D也不能选。
请再做下面一题(答案选B)：
He pointed to ______ looked like a tomb and said, “Ghost.”
A. that
B. what
C. which
D. as
3．“Is ______ you want to say?”asked the teacher.
A. this
B. that
C. all that
D. that all
【陷阱】根据中文字面意思误选A或B。
【分析】最佳答案选D。
假若选A或B，那么转换成陈述句即为：This is you want to say. / That is you want to say. 显然句中的两个谓语动词is与want 相冲突。
选D组成的句子是Is that all you want to say? 其中的that 为句子主语，all 为表语，you want to say 为定语从句，用以修饰all。
4. “When ______ leave for Japan?”“When ______ leave for Japan is kept secret.”
A. they will, will they
B. will they, they will
C. they will, they will
D. will they, will they
【陷阱】可能误选D，认为when 后应用疑问句词序。
【分析】最佳答案选B。
第一个when引出的是一个特殊疑问句，故用疑问词序；第二个when 引出的是主语从句，故其后用陈述句词序。
请做以下试题(答案选C)：
(1) None knows if _______ that boy, but if _______ him, her parents will be disappointed.
A. she will marry, she will marry
B. she marries, she marries
C. she will marry, she marries
D. she marries, she will marry
(2) “Where _______ go to work?”“Where _______ go to work is not known.”
A. we shall, we shall
B. shall we, shall we
C. shall we, we shall
D. we shall, shall we
5. Someone is ringing the doorbell. Go and see ______.
A. who is he
B. who he is
C. who is it
D. who it is
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为D。
首先可以排除A和C，因为空格处实为一个宾语从句，所以不能用疑问句词序。
另一方面，但按英语习惯，当用于指代身份不明的人时，要用代词it，而不用he 或she等。
比较以下两句：
Mr Smith is at the door. He wants to see you. 史密斯先生在门口，他想见你。
Someone is at the door. It may be the postman. 有个人在门口，可能是邮递员。
第一句因前面指明了是Mr Smith，所以后面用代词he；而第二句因前面用的是不定代词someone，说明此人身份尚不明确，故其后用了代词it 来指代。
